The Mesh::Feature class handles meshes. The Mesh.MeshFeature() function is for internal use only and cannot be used to create instances of this class. Therefore you must have a reference to a document, e.g. 'd' then you can create an instance with d.addObject(\"Mesh::Feature\"). Return the number of vertices of the mesh object Return the number of facets of the mesh object Adjust wrong oriented facets Smooth the mesh data Remove non-manifolds Remove non-manifold points Repair any invalid indices Remove degenerated facets Remove duplicated facets Remove duplicated points Repair self-intersections Remove folds on surfaces Remove points with invalid coordinates (NaN)
